This lot consists of two micro specimens of selectively epitactic “byssolite” on unusual tabular babingtonite from an old locality. The dimensions given are for the first specimen. The second specimen is 0.8 x 1.1 x 0.6 cm and also weighs next to nothing.

The first four photos are for the first specimen. FOV in the first pair of photos is 6.4 x 4.6 mm. The crystal on the right has a diameter of 2.6 mm. You will need 15X to view the crystals. But it is best to view this photos in stereo if you can. What may appear to be a single crystal on the right is actually two crystals at nearly right angles to one another. 

The next two photos (FOV 3.8 x 2.5 mm) zoom in on these two crystals.

The next four photos are for the second specimen. FOV in the first two of these photos is about 6.1 X 3.9 mm. These photos can be viewed in stereo under minID 33X-DK3. Fov in the next photo is   6.6 x 4.4 mm. The largest babingtonite xl is about 2.4 mm. As shown in the full-view photo, the matrix is pale green prehnite.

These specimens are old timers (found (September 1972) from a now somewhat obscure locality.

Combined shipping weight 2.9 oz. For non-USA destinations, up to a total weight < 8 oz, this can be combined with other items for the same postage. Within the USA, each additional ounce costs about $0.20.

Seller's terms and conditions

In addition to the standard terms and conditions, please note the following. Almost all IDs are visual. While in most cases the ID is obvious, there may be cases where it is not. If you are doubtful about a particular ID, please ask for more information. Or do not bid! Similarly, if you are not sure that the specimen meets your criteria, do not bid. I have tdone the best I can with the photos. Nevertheless, if you are not happy with a specimen for any reason, I will refund the bid price – but not the shipping costs (unless the fault is clearly mine) – if the specimen is returned. This policy applies even if analysis of the specimen shows that my ID was incorrect. When in doubt, ask - or don’t bid. Note that most crystals at MSH and Varennes are micros - even if on large specimens. Please pay attention to the stated sizes. Any customs duties, fees etc. are the responsibility of the buyer.
